LG hombot robot vacuum cleaner disassembly

It must be nice, in europe, having 240 volts for stuff like this.

I work with electronics all day. We have to think really hard to solve complex puzzles, sometimes under pressure from customers. I absolutely don't want to come home and battle buggy firmware and puzzle over someone else's bizarre user interfaces. Cord, switch, motor is the maximum level of complexity I want to manage when I'm not being paid to do it.

I use PCs at work, so I got my wife all Apple stuff, specifically so I can't be expected to help her with it.

Yea, well I made my living for a long time in broadcast, and 'the show must go on', and how the f*k you do it at that moment is less important. And that was in shifts too, 12 hour days... Increasing complexity, came from tubes to integrated circuits, 10 minutes is a long time but you need to fix something you have sometimes never seen before, and especially never used before... in less if possible. So its always fun to fix things, keeps the mind alive, had the diagnosis 100% right. I am not impressed by any of your complex designs as far as complexity goes, have you ever seen the circuit diagram of a color TV studio? And the equipment in it? Just wrote an other display driver today... between coffees, build the test hardware too.

Hey I need a new cordless drill. (my Makita is ~20 years old.) With Dad's day coming up some time soon... (the family never knows what to get me.) Do you have a favorite?

This is pretty complex:

PCIe interface, FPGA, ARM, several fiberoptic picosecond-resolution time stampers, 16 1-ns resolution fiberoptic pulse outputs (pretty clever, wish it was my idea), a piezo driver ARB, 16 fast energy sensor interfaces, system and PLC interfaces, Ethernet, 68 total connectors to the outside world. Lots of mixed analog and digital technologies.

OK now imagine a couple of thousand of boxes like that, all different of course, with miles and miles of cable interconnect, multiple control points, MW power consumption (all together) and thousands of people working with these, and flipped out screaming directors and a short timetable. And locations, size, remote, satellite links, and all on the tick of the clock, and you have a modern broadcast complex. Light, sound, video,

Yeah, this whole robot thing is highly overrated. Nobody would have a totally stone drunk sailor run a vacuum in their home. But, that is what the robot is, it just stumbles around until it hits something, then backs off and tries again.

Yeah, I'd never be able to get away with that! My wife didn't even know how to turn off her car alarm when she set it off. Some "helpful" people started pulling fuses out of the car, and she ended up driving for half a day with no stop lights and having to override the gearshift interlock. She had to call me so I could tell her "just lock and unlock the car with the key and it turns off the alarm."

I've got almost everybody running Linux of various versions, I do network backups when I get around to it, mostly it all works.

One of my favorite things is my Makita hammer drill. It came with a bonus angle grinder, both AC powered. The first floor walls of our cabin is concrete blocks with rerod and concrete fill. The combo makes holes in that nicely. I may add some windows.

I wouldn't enjoy that. The alpha males would be the producers and the "artists" and the "talent." Techs and engineers are peons in a culture like that. And I like to work on time scales of weeks and picoseconds, not minutes.

There's the same problem in companies started by scientists; EEs get little respect. It's usually better in companies founded by engineers.

Yup. Same in astronomy and biotech.

What's going on with with the large resistor?

I really like the Bosch drivers and drills. The 18V models are great but they're kinda heavy. The 12V are perfect for anything less than a #10x3" screw, give or take. The impact drivers are really slick. I'll never use a drill as a driver again.

I have the TS-55. Nice saw.

It's a lie. I'll *bet* you've never actually measured it in use. Think!

It's a lie. You will *never* hold that. Think, man!

This is not on 240V, it's battery operated, can run about 30 meter plywood before needing to be charged. For professional guys on jobs with no access to mains

I really don't want to argue with you, but you sure seem beyond reach

What do you want to bet?

Not so. I have a DeWalt that's quite nice on plywood and such. I also have an older Makita that's great for cedar siding. It sure as hell beats a 10lb. corded monster when you're trying to trim a piece of siding, 15' up a ladder on the side of the house. ;-)

A circular saw used on a tree? You must be suicidal. Cutting a 2" diameter branch with a 6" saw? You *have* to be! Haven't you ever heard of a chain saw, or even a reciprocating saw? ;-)

I've already won. You've obviously never measure it or you wouldn't be spouting such nonsense here. Hint: a full-sized cabinet saw is "only" 3HP, and weighs 600lbs.
